| | | | | | | | | | | | | | | | | | | | | | For easy multiplication using reverse subtract (when lit is 2^n-1) use the barrel shifter for rsb.

* | JIT: Combine add with shift and offset for array load & store.Anders O Nilsson2013-07-241-143/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimize long and double array load / store for ARM JIT. Array load / store performs a logical shift left and add, replace it with add capable of performing shift in the same instruction. Array load / store performs an add instead of using offset for vldr/vstr. Replace the add and vldr/vstr with a vldr/vstr that is capable of handling offset. This improves performance for usecases involving long and double array code execution in Dalvik. E.g WindowOrientation.

* Avoid sign extension in packed-switch.Elliott Hughes2012-07-171-7/+7
| | | | | | | | | | | | | | This code (at least in the ARM version) is trying to assign to r0 and r1 from C by returning a 64-bit result. The mistaken use of signed integers for pointers can lead to sign extension if the JIT code cache is at a sufficiently high address.

|\ | | | | | | | | * commit 'cf4a20cf0cbc53f03a5b16c7152bbb29907f7108': Interpreter/Debugger fix #4479968
| * Interpreter/Debugger fix #4479968buzbee2011-05-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This one was tricky to track down. The underlying problem arose with the consolidation of InterpState with Thread. Rather than having a state structure for each instance of the interpreter, we moved to a model that had a single thread-local struct shared by all interpreter instances running on that thread. A portion of interpreter state can't be shared - and thus was saved and restored on nested invocations of the interpreter. The bug here was that the storage for method return values was not included in the state that needed save/retore. In normal operation, it doesn't need to be saved - that storage isn't live across an invoke that could trigger a nested interpreter activation. However, when debugging, the debugger itself may hijack threads and create new interpreter instances for its own purposed - and there is a small window in which live retval can be trashed. The fix is simply to move retval into the InterpSave struct. Change-Id: Ib621824b799c5caa16fdfa8f5689a181159059df

| | | | | | | | | | | | | | | | | | | | The counted single stepping check should be based on the kSubModeCountedStep submode instead. Also since the NPC value is cleared when exceptions are thrown, we can single-step instructions that can throw as well. Change-Id: Idbc1307ae0956016ef76186aebc6e3b89b119d9d

* Local optimization fixes for diverences found by self verification.Ben Cheng2011-04-231-0/+2
| | | | | | | | | | | | | | | | | | 1) Only optimize each block once. Strictly speaking this is not a correctness issue however it triggers the subsequent problem. 2) Ignore dead instructions. 1: ldr r2, [r5, #8] 2: ldr r3, [r5, #8](nop) 3: str r3, [r5, #4] 4: movs r3, r2 When using instruction 1 to initiate redundant ld/st eliminations, if instruction 2 (which is already dead) is not ignored, it will be turned into a "mov r3, r2" and that will clobber r3 used by the str.
